You can’t run SQL server 2008 R2 over your existing SQL Server 2011 Denali in your PC. Before you want to run one, you have to remove another one from your system.

For remove the program, go to your control panel, then click on add or remove program. A list will be open then, that shows a list of the program that are running into your pc. Here you find the existing SQL server SQL Server 2011 Denali Click on remove button.

After removing it, you can run SQL server 2008 R2 in your pc. Keep it in mind that, you must have to follow a perfect installation process. Here I suggest you to visit two sites for your instance. Visit both for a better solvency.
